4.5 System Overview

In the previous sections we introduced the challenges of enterprise search and
how distributed search techniques can be used to solve the enterprise search prob-
lem. In this section we discuss the structure of an exemplary distributed enterprise
search system, PIA Enterprise [ 13 ], which is currently trialed at the administration
offices of the city of Berlin, Germany. The enterprise search system is built as a
multi-agent system (MAS). Our MAS-framework choice is JIAC release V [ 21 ],
an open source MAS-framework. By implementing our system as a MAS-system
